The density of sulphuric acid is ___ the density of water.

Q. Density of sulphuric acid is less than that of water.

Q. Various material and their density are given in column A and B. Predict which of the substance will float on water. Density of water is $1{\text{g/cm}}^3$.
$$\begin{array}{cc}\text{Material}& \text{Density}({\text{g/cm}}^3\text{)}\\ \text{Ice}& \text{0.98}\\ \text{Sulphuric acid}& \text{1.84}\\ \text{Kerosene}& \text{0.80}\\ \text{Plastic}& \text{1.05}\end{array}$$

Q. What volume of $98$% sulphuric acid (in ml) should be mixed with water to obtain $200mL$ of $15$% solution of sulphuric acid by weight? Given density of $H_{2}O=1.00gc{m}^{-3}$, sulphuric acid $(98$%) $=1.88gc{m}^{-3}$ and sulphuric acid $(15$%) $=1.12gc{m}^{-3}$.

Q. To find the relative density of sulphuric acid in an acid battery ______ is used.
