The answer is: 175 grams of fat are in the round.

m(ground round) = 1.33 ib.

First convert ib (pounds) to g (grams):

1 pound (lb) is equal to 453.592 grams (g).  

m(ground round) = 1.33 ib · 453.592 g/ib.

m(ground round) = 603.28 g.

ω(fat) = 29% ÷ 100%.

ω(fat) = 0.29; mass percentage of fat.

m(fat) = ω(fat) · m(ground round).

m(fat) = 0.29 · 603.28 g.

m(fat) = 175 g; mass of fat.

If ethanol has a density of 0.785g/mL, calculate the volume of 83.7 g of ethanol.
ratelena [41]

Answer:

<h2>106.62 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question

mass = 83.7 g

density = 0.785 g/mL

We have

volume =  \frac{83.7}{0.785}  \\  = 106.62420

We have the final answer as

<h3>106.62 mL</h3>
