You seem to have no idea of how to use the simplest formula

Do you know the formula to find concentration? C = n / V where n = moles and V = volume in L???

Well manipulat eht formula to find n. n = C x V. Why you would work on this all day is beyond lme. You did absolutely no research obviously.

For the second problem you need to know another EXTREMELY SIMPLE formula. n = m / M

moles = mass / molar mass so convert the 62.5 g of MgCL2 into moles then use the first formula above to find C.

1) Knowing this, the first problem can be solved by multiplying .62 L by the 2.0 M HCl, this is because 2.0 M=x/.62 L, where x is the number of moles of solute. Therefore, just solve for x, algebraically.

2) First, convert the gram value of magnesium chloride to moles by dividing 62.5 g by the molar mass of magnesium chloride, this is found by just adding the molar masses of magnesium to chloride.. Therefore, 62.5 g MgCl x (1 mole/Molar Mass of MgCl). Once you have the molar value of MgCl, just divide it by the given 1.50 L to find molarity.
