View lab report - molar mass of butane lab report from science organic ch at troy high school molecular mass of butane lab purpose: the purpose of this lab is to determine the molecular mass of.
Best answer: all you do is add up the molar masses of the carbons and hydrogens in the formula most peiordic tables show the molar masses of elements (also called their molecular weights) underneath their chemical symbols 4(molar mass of carbon) + 10(molar mass of hydrogen) = 4(120107 g/mol) + 10(100794. Gas laws and the molar mass of butane chem 30a the erlenmeyer flask is initially full of water the butane gas bubbles released from the butane cylinder displace the water in the flask, lowering the water level inside the flask (and raising the water level in the beaker. Weigh the disposable butane lighter to the nearest 001 g and record the mass 5 submerge the graduated cylinder (filled with water in the pneumatic trough.
Ap chemistry - molar mass of butane lab introduction: the molar masses of compounds are used daily in the chemistry profession molar mass is defined as the mass, in grams, of 1 mole of any element or compound so how is molar mass determined and how is the molar mass of an. The molar mass of ethane, which is represented by the chemical formula c2h6, is about 3006 grams per mole the molar mass can be derived from the sum atomic weight of each atom contained in the compound. Butane (/ ˈ b juː t eɪ n /) is an organic compound with the formula c 4 h 10 that is an alkane with four carbon atoms butane is a gas at room temperature and atmospheric pressure butane is a gas at room temperature and atmospheric pressure.
Conclusion by determining the molar mass of butane gas from experimental data, the chemical formula can be determined as well according to the experimental data gathered from this lab,the molar mass of the gas was 4230 g/mol, thus c3h8 was concluded to be the chemical formula. The molar mass of the butane gas was calculated by dividing the mass of butane gas in grams(020g) by the moles of butane gas(000352 moles) 020g/000352moles= 5681 g/mole= molar mass of butane gas. A) what is the molar mass of butane, c 4 h 10 b) calculate the mass of water produced when 880 g of butane reacts with excess oxygen c) calculate the mass of butane needed to produce 762 g of carbon dioxide. What is the molar mass of butane, c4h10 i got 5812 g/mol calculate the mass of water produced when 880 g of butane reacts with excess oxygen calculate the mass of butane needed to produce 762 g of carbon dioxide expert answer 100 % (3 ratings.
Determining the relative molecular mass of butane demonstration a sample of gas from a small pressurised cylinder is collected over water to measure the volume, and the mass found by the decrease in mass of the cylinder. Butane c4h10 molar mass, molecular weight endmemo home molar mass calculator. More information on molar mass and molecular weight in chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. Isobutane, also known as i-butane,2-methylpropane or methylpropane, is a chemical compound with molecular formula hc(ch 3) 3 it is an isomer of butane it is the simplest alkane with a tertiary carbon.
Molar mass of butane determined experimentally reminder – goggles must be worn at all times in the lab pre-lab discussion: in this particular lab, we are going to try to determine the molar mass of butane, c4h10, experimentallya. Finding molar mass starts with units of grams per mole (g/mol) when calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance the formula weight is simply the weight in atomic mass units of all the atoms in a given formula. As a current student on this bumpy collegiate pathway, i stumbled upon course hero, where i can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.
