Bonus Knowledge
To find the volume of the solution needed to provide 155 grams, you can use the formula
, where
is the mass and
is the density. Plugging in the values,
. So, rounding to one decimal place, the answer is
.
In chemistry, understanding the relationship between mass, volume, and density is crucial. This can be especially useful in labs where precise measurements are needed, such as when creating dilutions or mixing solutions. Knowledge of these concepts ensures you mix chemicals accurately for experiments or reactions without mishaps!
