A substance has a density of 6.26 g mL-1. What is the volume that a 2.49 g sample would occupy?

The answer is 0.4 mL

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

From the question

mass = 2.49 g

density = 6.26 g mL-1

So we have

We have the final answer as

0.4 mL

Hope this helps you

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

Answerd. may include all of these are many definitions of bases: the  brønsted-lowry definition of acids and bases says that bases are proton acceptors.the arrhenius definition of acids and bases says that bases increase [oh⁻] in solution (thereby producing oh⁻ ions)the lewis definition of acids and bases says that bases donate electron pairs.therefore, the sensible answer is that a base may include all of the described characteristics.
