Chemistry
2 answers:
Vsevolod [243]4 years ago
7 0
11.2L/22.4L (STP value) x 1 mol of CH4 x 16.04 g of CH4 = 8.2 g

Answer:  

7.91 g

Step-by-step explanation:  

1. Calculate the number of moles

STP is 0 °C and 1 bar .

One mole of a gas at STP has a volume of 22.71 L .

Moles of CH₄ = 11.2 L × (1 mol/22.71 L)

n = 0.4932 mol  

2. Calculate the mass of CH₄

Mass of CH₄ = 0.4932 × 16.03

Mass of CH₄ = 7.91 g

A student is interested in resource recovery through composting. Which field
sdas [7]
I think it’s microbiology, since it would help the student understand the process of composting the best. Botany is plants- not for composting. Geophysics- he’s not researching tectonic plates. Oceanography- he isn’t interested in the marina trench

Mechanical Advantage may be calculated using all of the following except ___.
kotegsom [21]
The only exception of calculating mechanical advantage is by multiplying resistance force by effort force. For example, in calculating the mechanical advantage of a lever, we consider its output and input forces. The equation would now be as follows:

Mechanical advantage = output force / input force
