A substance has a volume of 20 ml and a density of 2.5 g/ml. What is it mass? A:0.125g ,B:8g, c:22.5g or D:50g

D. 50g

volume : 20ml

= 0.02 l

density : 2.5g/ml

= 2500 g/l

therefore, p=m/v

m= p x v

= 2500 x 0.02

= 50

answer: glucose is broken down

explanation:

cellular respiration is a three stage process your body undergoes to produce atp. the first of these stages is called glycolysis.
