Density=mass/volume
Mass = 0.0500g
Volume = 6.40mL
0.0500g/6.40mL = 0.0078g/mL

<span>An enzyme is a protein, and proteins need certain temperatures to function optimally, or even function. Temperature may unfold the protein and may stop its functioning, or it may fold the protein into the correct formation to function. But by the way your question asks, EXCESS heat would denature the enzyme and cease function.</span>
Answer:
12
Explanation:
To get to this answer you have to look at the number first. So the given number is 12.47 and you need 2 sig figs.
To help you understand this more start off by underlining the first 2 numbers because 2 sig figs are needed. <u>12</u>.47
Now you want to look at the number after the underlined (I bolded that number). <u>12</u>.47
If the number is above 5 then you would round the previous number up by one but in this case it is 4 so you do not increase the number. Hence, you getting 12 as your final answer.
Hope this helped! Let me know if you have any questions.
