26, protons and nuetrons will always be the same
<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
1a: multiply by 10.
2.32*10
= 23.3 mm.
4a: divide by 10.
8.3/10
= 0.83 cg.
