Answer:
[tex]\%Mass =42\%[/tex]
Explanation:
Given
Sugar = 56g
Tea = 78g
Required
Determine the mass percent of the sugar
First we need to calculate the total mass
[tex]Total\ Mass = Sugar + Tea[/tex]
[tex]Total\ Mass = 56g + 78g[/tex]
[tex]Total\ Mass = 134g[/tex]
The percentage mass is then calculated as thus
[tex]\% Mass = \frac{Sugar}{Total\ Mass} * 100\%[/tex]
Substitute 56 and 134 for Sugar and Total mass respectively
[tex]\% Mass = \frac{56}{134} * 100\%[/tex]
[tex]\%Mass =0.41791044776 * 100\%[/tex]
[tex]\%Mass =41.791044776\%[/tex]
Approximate
[tex]\%Mass =42\%[/tex]
Hence, the percentage mass of sugar is 42%
