Calculate the grams of sugar present in a 355mL can of soda if the water in the can weighs 355g and the density of the soda is 1.10g/mL .

Question

aaronq · Answer

are we assuming the rest of the mass is only sugar?

anonymous · Answer

I'm not sure :/ because it says Express your answer to two significant figures and include the appropriate units. and the it says m=

aaronq · Answer

okay, i suppose so. So, first find the mass of the whole can, use the density, $\rho$, and the volume 335 mL.

                                $\rho=\dfrac{m}{V}$ 

subtract the mass of the water from the mass of the whole can.

                         $m_{sugar}=m_T-m_{water}$

Is it 353.9

aaronq · Answer

mass of sugar= (355 mL*1.10 g/mL)-335g= 55.5 g

anonymous · Answer

now i round of 55.5g to two sif fig?

aaronq · Answer

yes
