Question #177602

What is the molarity of 49 g of H_{2}SO_{4} dissolved in 0.3 L of solution?

Expert's answer

**Solution.**

"m=49g;"

"M(H_2SO_4)=98g\/mol;"

"V=0.3L;"

"M=\\dfrac{n}{V};"

"n=\\dfrac{m}{M(H_2SO_4)};"

"n=\\dfrac{49g}{98g\/mol}=0.5mol;"

"M=\\dfrac{0.5mol}{0.3L}=1.67M;"

** Answer:** "M=1.67M;"
