The formula relating density $D$`D`, mass $M$`M` and volume $V$`V` is $D=\frac{M}{V}$`D`=`M``V`. Calculate the density of a material that has a mass of $6.16$6.16g and a volume of $5.6$5.6cm^{3}.

Which cordial is stronger (has a higher concentration)?

The formula relating density $D$`D`, mass $M$`M` and volume $V$`V` is $D=\frac{M}{V}$`D`=`M``V`.

The density of Copper is $8.94$8.94 g/cm^{3}. If a sample of Copper has a volume of $26$26 cm^{3} and a mass of $M$`M` grams, solve for $M$`M`.
