Question

calculate
1)mass in grams of 5.8 mol N2O
2)number of moles in 8.0 grams of O2
3)molar mass if 11.2litres at stp weigh 8.5grams

Answer 1

Explanation:

1.gram atomic mass of N20 = 28+16 = 44

1 mole contains 44 g

so, 5.8 moles contain = (44×5.8)g

2. 32g = 1mole

8g = 8÷32 = 0.25 moles

3. 11.2 litres weigh 8.5g

so, 22.4 liters weigh = 8.5 × 2

= 17g

so molar mass = 17g
