Calculate the rate of gas production in cm3 g–1 min–1 during the first 40 minutes of thisinvestigation. Show your working.
Can anyone help me with this question I have tried and have got the wrong answer.
The markscheme is:
0.0155 / 0.016 = 2 marks;
0.0775 / 0.077 / 0.078 / 0.08 = 1 mark
/ 0.62 = 1 mark
Thank you
