To calculate your weight in Newton's simply use the following equation to solve for the weight.
Fg = m • g
Fg = 60 kg • 9.81 m/s^2
Fg = 588.6 kgm/s^2
Fg = 588.6 N.
Acceleration due to gravity on earth is 9.81 m/s ^2.

Molar mass of LiBr ( lithium bromide ) = <span>86.845 g/mol
</span><span>Amount of calculation to moles of lithium bromide (LiBr)
86.845 g ------------- 1 mole
100 g ----------------- ?
n = m / M
n = 100 / 86.845
n = 1.1514 moles of LiBr
V ---------------------1.1514 moles
1 L -------------------- 4 M
1.1514 * 1 / 4
V = 1151.4 / 4
V = 0,28785 L

Answer:
1.84 g/cm³
Explanation:
A flask has a mass of 78.23 g when empty and 593.63 g when filled with water. The mass of water is:
m(water) = 593.63 g - 78.23 g = 515.4 g
The density of water is 1.00 g/cm³. The volume of water (and the flask) is:
515.4 g × (1 cm³/1.00 g) = 515 cm³
When the same flask is filled with concentrated sulfuric acid, H₂SO₄, its mass is 1026.57 g. The mass of H₂SO₄ is:
m(H₂SO₄) = 1026.57 g - 78.23 g = 948.34 g
948.34 g of sulfuric acid occupy a volume of 515 cm³. The density of sulfuric acid is:
ρ = 948.34 g / 515 cm³ = 1.84 g/cm³
<span>Answer:
CO2→CO + 12O2 is not a balanced reaction, I think you meant to post " CO2→CO + 1/2O2"
The simple answer is that the enthalphy for reaction 1 reversed is the same enthalpy as for the reaction as written but with the opposite sign.
If A + B = AB with 30 kJ released then
AB = A + B with 30 kJ absorbed.
We would write it as
A + B = AB heat of reaction = -30 kJ
AB = A + B heat of reaction = +30 kJ</span>
