Question

can any one give me 10 questions of mole concept with solution in 10 minutes please ​

Answer 1

Answer:

here are a few of them and answers have been tick marked

Answer 2

1 no. of mol=0.5

mole =molar mass/mass of the substance

Mass=molar mass ×moles

14×0.5=7.0g.

2. 3.011×20^33/6.022×10^23=0.5mol

mass = 0.5×14=7.0g

3 1 mole of N2=6.022×10^23

N2=14×2=28g

4 No. of 0.1 mol of particles=6×10^23×0.1

= 6.022×10^22

5 atomic mass of sodium=23

given=46g

moles 46/23=2mol

Hope it will help you
