Westkost [7]

The first thing you should remember is that the energy in this case will be given by the work done.
The work is defined as:
W = F * d
Where
F = Force
d = displacement.
Calculate it.
5 kg x 9.8 m / s ^ 2 x 21 m = 1029 J

A chemist is using 351 milliliters of a solution of acid and water. If 14.1% of the solution is acid, how many milliliters of ac

stepan [7]

49.491 millimeters of acid is present

Solution:

Given that, chemist is using 351 milliliters of a solution of acid and water

14.1% of the solution is acid

To find: Milliliters of acid present

From given statement,

Solution of acid and water = 351 ml

14.1% of the solution is acid, which means that 14.1 % of 351 ml is acid

Therefore,

Milliliters of acid present = 14.1 % of 351 ml

Here "of" means multiplication

Therefore,

$\text{ Milliliters of acid present } = 14.1 \% \times 351$

$\rightarrow 14.1 \% \times 351\\\\\rightarrow \frac{14.1}{100} \times 351\\\\\rightarrow 0.141 \times 351 = 49.491$

Thus 49.491 millimeters of acid is present
