Hmm the answer should be D I just had that problem not to long ago on my worksheet :)
Answer:
1930g
Step-by-step explanation:
Mass = density × volume
Mass = 19.3×100 = 1930g
First, the dot stands for the "product". You have to multiply.
5/8* 2/7
= [5/ (2*4)]* (2/7)
= 5/4* 1/7 (because 2 and 2 cancel out)
= (5*1)/ (4*7)
= 5/28
The final answer is 5/28~
