425 mL
mass = 50.0 * 425
mass => 21250 mg
<span>There are a number of ways
to express concentration of a solution. This includes molarity. Molarity is
expressed as the number of moles of solute per volume of the solution. We do as follows:
Molarity = mol / L = 0.100 mol OH / L
0.100 mol OH / L ( .250 L ) ( 1 mol </span>Sr(OH)2 • 8 H2O / 2 mol OH ) ( 265.76 g / 1 mol ) = 3.322 g Sr(OH)2 • 8 H2O needed
GASES because they are unseeeable and the electricity cant catch them
