Question

Determine how many grams of each solute would be needed to make 2.60 *10^2 ml of a 0.100 M solution?
A) Cesium Iodide (CsI)
B) Sulfuric Acid (H2SO4)

I got an incorrect answer, can someone please explain how to work the problem?

Answer 1

you need to use 2 formulas; first find moles: \(Molarity=\dfrac{moles_{solute}}{L_{solution}}\)

then find grams (mass): \(moles=\dfrac{mass}{Molar\;mass}\)
