Calculate the mass of the salt contained in 500 g of its 12% solution.

m solution (salt) = 500 g
ω (salt) = 12%

To find:
m (salt) -?

1) Initial formula for calculations:
ω (salt) = m (salt) * 100% / m solution (salt);
2) Calculate the mass of salt in solution:
m (salt) = ω (salt) * m solution (salt) / 100% = 12% * 500/100% = 60 g.

Answer: The mass of salt in solution is 60 g.
