Answer:
The answer is A 83.33 g Ne
Explanation:
Used Avogadros Law
Answer: 0.33 moles
Explanation:
Given that,
Amount of moles of Na2CO3 (n) = ?
Mass of Na2CO3 in grams = 35g
For molar mass of Na2CO3, use the molar masses as follows:
Sodium, Na = 23g;
Carbon, C= 12g
Oxygen, O = 16g
Na2CO3 = (23g x 2) + 12g + (16g x 3g)
= 46g + 12g + 48g
= 106g/mol
Since, n = mass in grams / molar mass
n = 35g / 106g/mol
n = 0.33mole
Thus, 0.33 moles of Na2Co3 is needed to produce 35g of Na2Co3
Answer:
A measurement is the action of measuring something, or some amount of stuff. So it is important to measure certain things right, distance, time, and accuracy are all great things to measure. Measurements can also allow us to make desicions based on the outcome of the measurement
