There are many compounds with a relative mass of 72.
Eg. pentane (C5H12), methyl butane (CH3)-(C4H9), dimethyl propane (CH3)2-(C3H6). Inorganic formula's can not easily be guessed, but undoubtly be found.
Only one (isotope of an) element has the relative mass of 72: Gallium, (Ga-72), but this is not a natural, stable isotope. Gallium has not a molecular formula (being a metal like aluminum) only an atomic symbol: Ga.

What is the formula mass of C6H12O6?
The formula mass of C6H12O6 (glucose) is calculated by summing the atomic masses of the elements in the compound. The atomic masses of carbon (C) is 12.01, hydrogen (H) is 1.01, and oxygen (O) is 16.00. Hence, the formula mass of C6H12O6 is (6 * 12.01) + (12 * 1.01) + (6 * 16.00) = 180.16 g/mol.
What is the molar mass of 2-pentanone?
Pentane has the molecular structure C5H12 So multiply the number of each atom with its molecular mass. (see the periodic table) 5*12 + 12*1 = 72 gram per mole. Or more accurately: 5*12.01078 + 12*1.007947 = 72.149264 g/mole
What percentage of each glucose molecule is made up of carbon?
* Percentage mass = atomic mass of required element/ total mass of compound. * Glucose is represented by the formula C6H12O6. The relative molecular mass (Mr)= (6 x 12) + (12 x 1) + (6 x 16) = 180. # Let's start with carbon: one atom of carbon has an atomic mass of 12, but there are 6 atoms of carbon in an molecule of glucose. 6 x 12 = 72. Divide this by 180 and multiply by 100 to give 40%. # Next, we have hydrogen. Each atom has an atomic mass of 1. Multiply by 12 to give 12. Then divide by 180 and multiply by 100, to give 6.6% # Finally, there's oxygen. One atom of oxygen has an atomic mass of 16, so multiply 16 by 6, which gives 96. Divide this by 180, then multiply by 100 to give 53.3%. * To check that these % masses are correct, add the percentages to ensure they make 100: 40 + 6.6 + 53.3 = 99.9%, which is close enough!

How many moles are in 72g of Calcium Sulphate?
To calculate the number of moles in 72g of Calcium Sulphate (CaSO4), we need to know the molar mass of CaSO4, which is approximately 136.14 g/mol. Then use the formula: moles = mass / molar mass. So, moles = 72g / 136.14 g/mol ≈ 0.53 moles of CaSO4.

How do you calculate moles to grams?
Use the equation. moles = mass(g) / Mr The 'Mr' is the Relative Molecular Mass of any substance. You take the Atomic masses from the Periodic Table. So taking water as an example The formula for water is H2O From this formula we know that there are two(2) hydrogen(H) atoms and one(1) oxygen atom(O). From the Periodic Table the atomic mass of 'H' is '1' and the atomic mass of 'O' is '16'. So using the formula and the masses we have 2 x H = 2 x 1 = 2 1 x O = 1 x 16 = 16 We then add these two numbers. 2 + 16 = 18 . '18' is the 'Mr' of water (H2O). So calculating the number of moles of water in say 72 grams. Substitute in moles(H2) = 72 g / 18 moles(water). = 4 NB Since pure water at STP(Room temperature and air pressure) the scientific standard is 1 gram = 1 cm^(3) So if you have a measuring cylinder, and put into it 72 cm^(3) of water , you have 72 grames of water, and by the above calculation , you also have 4 moles of water. NNB moles = mass(g) / Mr This is a mathemtical equation and can be algebraically rearranged to Mass(g) = moles X Mr or Mr = mass(g) / moles. Hope that helps!!!!!
