Question

A medium-sized carrot weighs 64 g and contains 7.0 g of carbohydrate.

What percent, by mass, of the carrot is carbohydrate? Express your answer using two significant figures.

Answer 1

The percent, by mass, of carbohydrate in a medium-sized carrot is approximately 10.9%.

Step-by-step explanation:

To find the percent, by mass, of carbohydrate in a medium-sized carrot, we can use the following formula:

Percent mass of carbohydrate = (mass of carbohydrate / total mass) × 100

In this case, the mass of carbohydrate is given as 7.0 g and the total mass of the carrot is 64 g. Plugging these values into the formula:

Percent mass of carbohydrate = (7.0 g / 64 g) × 100 = 10.9%

Therefore, approximately 10.9% of the carrot's mass is carbohydrate.

Answer 2

10,93% of a carrot is carbohydrate.

Step-by-step explanation:

In order to solve this you just have to create a rule of three where 64g is the 100% and you want to calculate how much is 7g in percentage:

`(64)/(100)= (7)/(x)\\ x=(7*100)/(64)\\ x=10,9375`

So there are 10.9375 % carbohydrates in a piece of carrot.
