If 35.0 mL of water in a graduated cylinder is displaced by 8.00 mL
sdas [7]

Answer:

<h2>0.52 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

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

From the question

volume = final volume of water - initial volume of water

volume = 35 - 8 = 27 mL

We have

density =  \frac{14}{27}  \\  = 0.518518...

We have the final answer as

<h3>0.52 g/mL</h3>

Angelina_Jolie [31]

Answer:

3.5 pill need to taken for completing dosage of 875 mg

Total weight of one pill = 250 mg

Number of pills required is equal to total dosage of medicine divided by the weight of one pill.

Hence,

Number of pills

= \frac{875}{250} \\= \frac{175}{50} \\= \frac{35}{10} \\= 3.5
