Question

What is the molar mass of a compound if 1.2 g of this compound was used to prepare a 250 mL of a 0.016 M solution.​

Answer 1

Answer:

an iron nail is kept in tap water for few

days,

Is it a chemical or physical change?

Please answer

Answer 2

0.3 g

Explanation:

Molarity= no. of moles of solute =0.016=n÷250

volume of solution in ml

so, no. of moles of solute= n= 4

no. of moles = given mass÷ molar mass

4= 1.2÷ molar mass

molar mass=0.3g
