Question

You are making sweet tea. You add 56 g of sugar into 78 g of tea. What is the

mass percent of sugar?*
79%
42%
72%
ОО
56%

Answer 1

`\%Mass =42\%`

Step-by-step explanation:

Given

Sugar = 56g

Tea = 78g

Required

Determine the mass percent of the sugar

First we need to calculate the total mass

`Total\ Mass = Sugar + Tea`

`Total\ Mass = 56g + 78g`

`Total\ Mass = 134g`

The percentage mass is then calculated as thus

`\% Mass = (Sugar)/(Total\ Mass) * 100\%`

Substitute 56 and 134 for Sugar and Total mass respectively

`\% Mass = (56)/(134) * 100\%`

`\%Mass =0.41791044776 * 100\%`

`\%Mass =41.791044776\%`

Approximate

`\%Mass =42\%`

Hence, the percentage mass of sugar is 42%
