Molarity calculations

A $0.674\,\text M$0, point, 674, start text, M, end text cobalt(II) chloride ($\text{CoCl}_2$start text, C, o, C, l, end text, start subscript, 2, end subscript) solution is prepared with a total volume of $0.0750\,\text{L}$0, point, 0750, start text, L, end text. The molecular weight of $\text{CoCl}_2$start text, C, o, C, l, end text, start subscript, 2, end subscript is $128.9\,\dfrac{\text{g}}{\text{mol}}$128, point, 9, start fraction, start text, g, end text, divided by, start text, m, o, l, end text, end fraction.
