Answer:
c
Explanation:
it makes sense and the diagram is build like that with high tech
Answer: See below
Explanation:
n of CO2 = 0.364mmol
Mass of C = 0.364*12 = 4.368 mg
n of H2O = 184.37 = 0.243 mol
The compound has 2*0.243mmol of H
Mass of H = 0.486 mg
Mass of O = 10.68 − (4.368+0.486) = 5.826mg
Moles of O = 0.364
<u>C:H:O Ratios</u>
0.364 : 0.486 : 0.364
= 1 : 1.34 : 1
= 3 : 4 : 3
<u>So the empirical formula is C3H4O3,</u>
Empirical formula mass
= 88= 2 × Molar mass
<u>And the molecular formula is C6H8O6</u>

Answer: 0.462 moles
Explanation: 13C indicates an isotope of carbon and its mass number is 13. It means the mass of 1 mol of 13C is 13 gram.
The question asks to calculate the number of atoms present in 6.00 grams of 13C.
To calculate the number of moles we divide the given grams by the mass of 1 mol of the element. The set could be shown easily using dimensional analysis as:

= 0.462 moles
So, there will be 0.462 moles of atoms in 6.00 grams of 13C.
Answer:
They all have the same number of atoms
Explanation:
Which of the following has more atoms?
One mole of zinc
One mole of gold
One mole of silver
One mole of magnesium contians
O They all have the same number of atomst
a mole of anything contains Avogadros number of 6.022X10^23 things
which has the greatest number of thing? a dozen eggs, a dozen cookies, a dozen pizzas?
a dozen is a number means 12
a mole is a number that that means 6.022 X 10^23 you calculate the molar mass from the chemical formula, but every j mole contains 6.022X10^23
particles.
just like every dozen contains 12
so
They all have the same number of atoms
