Question 49

An ecological study was conducted to investigate the water absorption capacities of four different moss species ( $A$ , $B$ , $C$ , and $D$ ) sampled from a temperate rainforest canopy.

The results of the field measurements are presented below:

Moss species	$A$	$B$	$C$	$D$
Initial dry mass / g	8.0	15.0	12.5	20.0
Volume of water absorbed / $cm3\text{cm}^3$	4.4	12.3	9.5	11.2
Final mass of wet moss / g	12.4	27.3	22.0	31.2

Calculate the percentage increase in mass for moss species C.
