Calculate the number of moles and molecules of acetic acid in 22gm of it

aivan3 [116]

Answer:

0.366 moles to the nearest thousandth.

Explanation:

The molar mass of acetic acid CH3COOH = 2*12 + 4(1.008) + 2*16

= 60.03 g so the number of moles in 22 g

= 0.366.

The maximum amount of nickel(II) cyanide that will dissolve in a 0.220 M nickel(II) nitrate solution is...?

sweet [91]

Answer : The maximum amount of nickel(II) cyanide is $5.84\times 10^{-12}M$

Explanation :

The solubility equilibrium reaction will be:

$Ni(CN)_2\rightleftharpoons Ni^{2+}+2CN^-$

Initial conc. 0.220 0

At eqm. (0.220+s) 2s

The expression for solubility constant for this reaction will be,

$K_{sp}=[Ni^{2+}][CN^-]^2$

Now put all the given values in this expression, we get:

$3.0\times 10^{-23}=(0.220+s)\times (2s)^2$

$s=5.84\times 10^{-12}M$

Therefore, the maximum amount of nickel(II) cyanide is $5.84\times 10^{-12}M$

What is the mass of 4.2kg gold when it's transferred to a planet having twice the gravity of earth

rjkz [21]

Answer:

The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).
