Answer:
Mass = 0.158 g
Explanation:
Formula used,
P V = n R T
Or,
n = P V / R T
Putting values,
n = 0.948 atm . 0.025 L / 0.0821 L.atm.K⁻¹.mol⁻¹ . 291.45
n = 0.00099 mol
Note: we have changed pressure from mmHg to atm, volume from mL to L and temperature from C to K)
Also,
Mass = n . Molecular Mass
Mass = 0.00099 mol × 159.808 g/mol
Mass = 0.158 g
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.

Answer:
An Educated Guess
Explanation:
After the scientist is done with the experiment he should do an educated guess, they use the data from the experiments to make charts and graphs to communicate the results of the experiment. After the scientists makes the hypothesis, they perform this procedure.
10% is normally how it works .
For example like 1,000 is the top the next level would be 100 then the next would be 10
Answer:
the sum is Rs 4,200
Explanation:
Given that
3 by 7 of the sum is $1,800
We need to find out the sum
So,
Here we assume the sum be x
So the following equation should be made
3 ÷ 7 × x = 1800
3x = 1800 × 7
x = (1800 × 7) ÷ 3
= Rs 4,200
Hence, the sum is Rs 4,200
The same would be considered and relevant
