The molecular formula of the liquid​ : C₆H₁₂

<h3>Further explanation</h3>

Given

molar ratio C H = 1.2 : 0.12

0.12 g at STP gave 32 cm³(0.032 L)

Required

The molecular formula

Solution

At STP, 1 mol = 22.4 L, so for 0.032 L :

mol = 0.032 : 22.4

mol = 0.00143

Molar mass (M) of liquid :

M = mass : mol

M = 0.12 g : 0.00143 mol

M = 83.92≈84 g/mol

C : H = 1 : 2

(CH₂)n=84

(12+2.1)n=84

(14)n=84

n=6

(CH₂)₆=C₆H₁₂

A student has a mass of 90 kg what would his weight be on mars if the acceleration due to gravity is 3.7 ?
Mumz [18]

Answer:

333N

Explanation:

Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to. Being that Mars has a gravitational force of 3.7m/s2, we multiply the object's mass by this quantity to calculate an object's weight on mars.

So an object or person on Mars would weigh 37.83% its weight on earth. Therefore, a person would be much lighter on mars. Conversely, a person is 62.17% heavier on earth than on Mars.
