How many grams of CaCl2 are in 250 ml of 2.0 M CaCl2?

How many grams of CaCl2 are in 250 ml of 2.0 M CaCl2? The answer is: ” 56 g CaCl₂ ” . 2.0 M CaCl₂ = 2.0 mol CaCl₂ / L ; Since: “M” = “Molarity” (measurement of concentration); = moles of solute per L {“Liter”} of solution.

How many moles are in 50 grams of ch4?

So let’s calculate how many moles are in 50 g of CH4 by dividing it’s mass by it’s molar mass (16 g/mole). I get 3.125 moles. The equation says we should get the same number of moles of CO2, so set moles CO2 = 3.125 moles. Then we can find the mass of CO2 by multipying by the molar mass of CO2 (44 g/mole).
