The actual yield of a certain reaction is 44.0 g, while the theoretical yield is 50.0 g. Calculate the percent yield.
Goshia [24]
Percent yield represents to what extent the reaction runs to completion. In this, the theoretical yield is 50 grams (100% completion).

To calculate percent yield, divide the actual by the theoretical. In doing so, the percent yield is 88% (44/50).

A sample of metal has a mass of 16.5916.59 g, and a volume of 5.815.81 mL. What is the density of this metal
Oxana [17]

Answer:

=> 2.8554 g/mL

Explanation:

To determine the formula to use in solving such a problem, you have to consider what you have been given.

We have;

mass (m)     = 16.59 g

Volume (v) =  5.81 mL

From our question, we are to determine the density (rho) of the rock.

The formula:

p = \frac{m}{v}

Substitute the values into the formula:

​p = \frac{16.59 g}{5.81 mL} \\   = 2.8554 g/mL

= 2.8554 g/mL

Therefore, the density (rho) of the rock is 2.8554 g/mL.
