How many mol of C7H16 would you have if you have 76.36 grams? Give your answer to 2 decimal spaces.
1 answer:
0.761 mol of would you have if you have 76.36 grams.
A mole is defined as 6.02214076 × of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
Given data:
Mass=76.36 grams
Moles = 0.761
Hence, 0.761 mol of would you have if you have 76.36 grams.

The volume of chlorine molecules produced at STP would be 96 dm³.
<h3>Stoichiometric problem</h3>Sodium chloride ionizes during electrolysis to produce sodium and chlorine ions as follows:
This means that 1 mole of sodium chloride will produce 1 mole of sodium ion and 1 mole of chlorine ion respectively.
Recall that: mole = mass/molar mass
Hence, 234 g of sodium chloride will give:
234/58.44 = 4.00 moles.
Thus, the equivalent number of moles of chlorine produced by 234 g of sodium chloride will be 4 moles.
Recall that:
1 mole of every gas at Standard Temperature and Pressure = 24 Liters.
Hence:
4 moles of chlorine = 4 x 24 = 96 Liters or 96 dm³.
