Answer:

\boxed {\tt 944.748 \ grams}

Explanation:

The formula for density is:

d=\frac{m}{v}

Rearrange the formula for mass, m. Multiply both sides by v.

d*v=\frac{m}{v} *v

d*v=m

Mass is found by multiplying the mass by the volume.

The density of the gold is 19.32 grams per cubic centimeter. The volume is 48.9 cubic centimeters.

d= 19.32 \ g/cm^3 \\v=48.9 \ cm^3

Substitute the values into the formula.

m= 19.32 \ g/cm^3 *48.9 \ cm^3

Multiply. Note the centimeters cubed will cancel out.

m= 19.32 \ g * 48.9

m= 944.748 \ g

The mass of the gold is 944.748 grams.

What volume of 0.350 m koh is required to react completely with 24.0 ml of 0.650 m h3po4?
BartSMP [9]

The complete balanced chemical equation for this is:

<span>3KOH  +  H3PO4  -->  K3PO4  +  3H2O</span>

 

First we calculate the number of moles of H3PO4:

moles H3PO4 = 0.650 moles / L * 0.024 L = 0.0156 mol

 

From stoichiometry, 3 moles of KOH is required for every mole of H3PO4, therefore:

moles KOH = 0.0156 mol H3PO4 * (3 moles KOH / 1 mole H3PO4) = 0.0468 mol

 

Calculating for volume given molarity of 0.350 M KOH:

Volume = 0.0468 mol / (0.350 mol / L) = 0.1337 L = 133.7 mL

 

Answer:

<span>133.7 mL KOH</span>
