Answer:
<h2>The answer is 50 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 50 mL
density = 1g/mL
The mass of the liquid is
mass = 50 × 1
We have the final answer as
50 g
Hope this helps you
The girl should first prevent getting scammed. She shouldn’t be sharing any personal information about herself or anybody else. Then to try to prove, she can maybe ask to face time during the day, or asks him out to go somewhere(park,movies,etc.,) but make sure you take someone with you like a trusted adult or someone older, and if he keeps making excuses and denying then it’s pretty clear it’s a catfish.
Moles are the ratio of the mass and the molar mass of the substance given and is estimated in mol. The moles that the lungs contain when it is full is 0.12 moles.
<h3>What is the relation of the volume and moles?</h3>
Moles of the substances are directly proportional to the volume of the substance and can be shown as,

Here,
Initial volume
= 2.9 L
Final volume
= 1.2 L
Initial moles = 
Final moles
= 0.049 mol
Substituting values in the equation:

Therefore, the number of moles in the lungs are 0.12 moles.

The question is incomplete, the complete question is:
The element tin has the following number of electrons per shell: 2.8. 18, 18, 4. Notice that the number of electrons in the outer shell of a tin atom is the same as that for a carbon atom. Therefore, what must be true of tin? Tin is a polar atom and can bind to other polar atoms. Tin has a high molecular weight to give tin-containing molecules greater stabilty. All of the above Tin conform single covalent bonds with other elements, but not double or triple covalent bonds Tincan bind to up to four elements at a time
Answer:
Tin can bind to up to four elements at a time
Explanation:
Certain important points were made in the question about tin and one of them is that tin is an element in the same group as carbon hence it has the same number of valence electrons as carbon.
Carbon is always tetra valent. The tetra valency of carbon is the idea that carbon forms four bonds.
If tin has the same number of valence electrons as carbon, then, tin can bind to up to four elements at a time
Two things plants need to have in order to stay in orbit and rotate is speed and less velocity.
