Answer:
The number of sulfur atoms in 1 g of sulfur is:- 
atoms
Explanation:
Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by 
.
Avogadro constant:-
Given atomic mass of sulfur = 32 u
Which means that:-
32 g of sulfur contains 
of atoms
Also,
1 g of sulfur contains 
of atoms
<u>So, The number of sulfur atoms in 1 g of sulfur is:- atoms</u>
Subtracting the mass of (flask+water) from the empty flask gives:
95.023 g - 85.135 g = 9.888 grams of water
Dividing this by the given volume of 10.00 mL water gives:
9.888 grams of water / 10.00 mL of water = 0.9888 g/mL of water
Therefore, based on this sample, the density of water is 0.9888 g/mL, which is close to the usually accepted approximation of 1 g/mL.
Answer:
I believe its A
Explanation:
A molecule that has a symmetrical shape will be a nonpolar molecule.
The letter in parentheses after a chemical formula indicates c) the physical state of the substance.
The letters can be:
→ (s) for solid.
→ (l) for liquid.
→ (g) for gazeous.
→ (aq) for an aqueous solution (like NaCl (aq) - NaCl is dissolved in water)
