Molarity = mol/L
500 mL = 0.5 L
342.34 g/mol * 0.462 mol/L = 158.16 g/L
158.16 g/L * 0.5 L = 79.1 g of sucrose is needed to create a 0.462 M solution.
Not at all they’re poisonous
Yes metamorphic rocks melt in hot fluid
MFe: 56 g/mol
..........
56g ----- 1 mol
5g ------- X
X = 5/56 = 0,089 moles of Fe
56g ----- 6,02×10²³ atoms
5g ------- X
X = (5×6,02×10²³)/56
X = 0,5375×10²³ = 5,375×10²² atoms of Fe
