Question

Ba has a density of 3.5 g/ml. what would the mas of a rectangular block of Ba with the dimensions, 1cm *3cm *5cm?

Answer 1

Step-by-step explanation:

We are given: density of Ba = 3.5g/mL

: dimensions of Ba = 1cm, 3cm , 5cm

Therefore, volume of Ba = 1*3*5 = 15cm^3 = 15ml

`\begin{gathered} \rho\text{ = }(m)/(V) \\ \\ \therefore m\text{ = }\rho V \\ \\ \text{ = 3.5}*15 \\ \\ \text{ = 52.5g} \end{gathered}`

Answer:

Mass of Ba is 52.5g.
