You would use the formula:
n =
Where m is the mass, and M is molar mass (the periodic table would be used for this)
In this case, we need to rearrange the formula to find m
m = nM
= 5.40 x 6.941
= 37.5g
Hope this helped! Ask me if there's any part of the working you don't understand :)
Anyone can use it it involves asking questions.observing and and inferrring experimenting and collecting datafinding evidence drawing conclusions
Answer:
Sound travels over 4 times faster in the ocean than it does on land.
Explanation:
Speed of sound in water is approximately 1500 meters per second
and the speed of sound in air is approximately 340 meters per second.

The pH scale is a measure of acidity. It ranges from 1 (the most acidic) to 7 (neutral) to 14 (the most basic). It is used to measure solutions for how acidic or basic (a base is the opposite of an acid) they are, and is based on the concentration of H+ or OH- ions. I hope this helps.
Answer:
base drugs
Explanation:
The pH scale is a scale graduated from 0-14. It is used as an indicator of the degree of acidity or alkalinity. A pH of 0-6.9 indicates acidity. A pH of 7 indicates that the solution is neutral. A solution of pH above 7 indicates that the substance is basic.
It is thus a correct statement to say that any substance that dissolves in solution to produce a solution of pH greater than 7.0 is a basic substance.
If we look at the options closely, it is only a basic drug that will dissolve in water to yield a basic solution of pH greater than 7.0 hence the answer.
