Question

calculate the masses of the following- 5 moles of ammonia,0.5 moles of water,1.50 moles of Na+ ions​

Answer 1

weight of 1 mole of anything = molar mass

Molar mass of NH3 (ammonia)= 14+1+1+1= 17g

5 moles ammonia = 5 x 17 = 85g

Molar mass of H2O (water) = 16 + 1 +1 = 18g

0.5 mole H2O = 9g

Molar mass Na+ = 23g

1.5 mole = 34.5g

Hop you have understood fam

Answer 2

Please check the answer of the previous question asked by you on brainly......!!!!

Let's start this question ....!!!!

✳️ 1 mole of ammonia weighs 17g. So, 5 moles of ammonia will weigh (17×5) g = 85 g.

✳️ 1 mole of water weighs 18 g. So, 0.5 mole of water will weigh 9 g.

✳️ 1 mole of sodium ion weighs 22.989769 g or 23 g (approx.) So, 1.50 moles of Sodium ion will weigh 34.5 g.
