Question

Calculate the number ofmoles present in each sample

a,44.8 L ammonia at Stp
b,900 g Water ( molecular mass of water is 18g)​

Answer 1

Answer:

44.8 l of NNH3 at STP

Number of moles in molecules =44.8/22.4 =2

Number of molecules =2×6.022×10²³

Number of atoms =4×2×6.022×10 ²³

=8×6.022×10 ²³
