Study the concentration amount shown on the juice label. then answer the question. if you had 100 ml of juice, how many milliliters would be fruit juice?

a.
25 ml
b.
2.5 ml

c.
75 ml

d.
250 ml

If the liquid is, say, 50% concentration, that means that, in this case, 50 milliliters would be a fruit juice, while the other 50% would be of other stuff. So look at the concentration marking. It will be a percentage that many milliliters will be of fruit juice--75%=75 milliliters, and so on, because there is an even 100mL of juice. 

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.
