Answer:

Density = 19.3 g/cm³

Explanation:

D = m/v

m = 965 g

v = 50 cm³

so,

965 g / 50 cm³ = 19.3g/cm³

Hope this helps!

117 milligrams (mg) of purified product was isolated from a chemical reaction. This experimental yield of product represents a 8
Brut [27]

Answer:

131 mg

Explanation:

Percent yield = 89%

Actual yield = 117 mg

Percent yield is given by

\text{Percent yield}=\dfrac{\text{Actual yield}}{\text{Theoretical yield}}\times 100\\\Rightarrow 89=\dfrac{117}{\text{Theoretical yield}}\times 100\\\Rightarrow \text{Theoretical yield}=\dfrac{117}{89}\times 100\\\Rightarrow \text{Theoretical yield}=131.46\approx 131\ \text{mg}

The theoretical yield, for this reaction is 131 mg.

Calculate the mass of arsenic(III) chloride produced when 0.150 g of arsenic reacts with excess chlorine according to the equati
adell [148]

Answer:

0.363 g

Explanation:

2As + 3Cl₂      →   2AsCl₃

calculate the number of moles of arsenic

Number of moles = mass/ molar mass

Number of moles =  0.150 g/ 75 g/mol

Number of moles = 0.002 mol

compare the moles of arsenic with arsenic chloride.

                         As             :             AsCl₃

                          2              :                2

                        0.002        :              0.002

Mass of arsenic chloride produced:

Mass = number of  moles × molar mass

Mass = 0.002 × 181.28 g/mol

Mass = 0.363 g
