Answer:
A. 0.17 moles
Explanation:
Every 10 grams Glucose to mol = 0.05551 mol
30 moles= 0.166503, round up to .17
There are 0.54 moles of sodium carbonate are contained by 57.3 grams of sodium carbonate.
we can calculate number of moles in a compound by dividing number of grams of compound by the molar mass of the compound.
molar mass of sodium carbonate = 105.987 g/mol
now, 57.3 / 105.987 = 0.54 moles
