Answer:
The mass of butter is 1849 g.
Explanation:
Given data:
Specific gravity of butter = 0.86
Volume = 2.15 L
Mass = ?
Solution:
Specific gravity of a substance is the ratio of density of substance divided by the density of water.
Thus the density of butter is 0.86 g/mL
Formula:
Conversion from L to mL
2.15 /1000 = 2150 mL
d = m/v
0.86 g/mL = m/2150 mL
m = 1849 g
Thus the mass of butter is 1849 g.
[H3O+] = 10^-pH.
[H3O+] = 10^(-2,5) = 0,0032 moles/dm3
How many moles of ammonia are produced when 6 moles of hydrogen gas react with nitrogen gas? What are some simple steps I can take to protect my privacy online? 6 * 2/3 moles of ammonia must be produced. Therefore 4 moles of ammonia can be produced
Answer:
126.5g
Explanation:
n=<u>m</u><u> </u>
M
where n is moles
m is mass of substance
M is molar mass
molar mass of sodium is 23g/mol
m=nM
m=5.5(23)
m=126.5
if the ph is above 7 then its acidic
if its below 7 than its going to be basic.
