Answer : The pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
Explanation :
As we are given that the atmospheric pressure is, 745 mmHg.
Now we have to determine the pressure in torr and atm.
Conversions used:
1 atm = 760 mmHg
1 atm = 760 torr
1 mmHg = 1 torr
As, 760 mmHg = 1 atm
So, 745 mmHg =
and,
As, 1 mmHg = 1 torr
So, 745 mmHg = 745 torr
Therefore, the pressure in torr and in atmospheres are, 745 torr and 0.980 atm respectively.
The specific heat of silver is calculated as below
Q(heat) = M(mass) xC(specific heat capacity)
Q= 42.8 j/c
M=181 g
C=?
by making C the subject of the formula
C= Q/M
C= 42.8 j/c/181 g =0.236j/g/c
6.02x10^22 is one mole, so we can just say it's 1 mol HCl in 2.0 L of water. Molarity is mol/L, so 1 mol/2 L is 0.5 mol/L or 0.5 M. Make sense?
Add up all the grams to get 9.96, then divide the amount if each element by the total;
4.56 of Pb divided by 9.96 = 0.4578313 now multiply by 100 and get 45.8% of Pb, then do the same for the rest of the elements, hope this helped <3
