CIE Chemistry Doubts Here

[RatJumper]

Guys, for AS chemistry in practicals, when they tell us to calculate answers in which we have to use q=mc(delta)t, i know that c=4.2, (delta)t is easy to calculate from our results, but m, i have no idea where to get it from :/ All i have are the volumes and not masses. Can i use volumes for the value of m in the equation?

If this isn't clear, i am basically referring to S10 P33 Chemistry (9701) question 1(c)(i).

Thankx

In such questions, whatever the volume is given we use that as mass.

Just remember, we will need to input the mass/volume of the substance whose temperature is rising.

Hope this helps
