Explanation:

Neptune a gaseous planet. It is the planet furthest from the Sun being at an approximate distance of 4,500 million kilometers, its mass is 1,0241 x 10^26 kg. Neptune is composed of ice and rock, with a heavy and solid core similar to Earth's. It does not have a solid surface. It is a dense planet and its magnetic field is 27 times stronger than Earth's. Neptune has an atmosphere of 74% hydrogen, 25% helium and 1% methane.

Answer: n=15.56moles

Explanation:

PV = nRT

where  

P is pressure in atmospheres

V is volume in Liters

n is the number of moles of the gas

R is the ideal gas constant = given as (0.0821L -atm/k-mol

PV = nRT

n= PV/RT

n= (1.5 X 230)/ (0.0821  X 270)

n= 15.56 moles

Zn-64 = 48.63%
sladkih [1.3K]

Answer:

A = 65.46 u

Explanation:

Given that,

The composition of zinc is as follows :

Zn-64 = 48.63%

Zn-66 = 27.90%

Zn-67 = 4.10%

Zn-68 = 18.75%

Zn-70 = .62%

We need to find the  average atomic mass of the given element. It can be solved as follows :

A=\dfrac{48.63\times 64+27.90\times 66+4.1\times 67+18.75\times 68+0.62\times 70}{100}\\A=65.46\ u

So, the average atomic mass of zinc is 65.46 u.
