(d) How many grams of CaO can be produced?

Chemistry
1 answer:
Hunter-Best [27]1 year ago
3 0

218.4 grams of CaO is produced using 3.9 moles CaCO₃.

<h3>How we calculate weight of any substance from moles?</h3>

Moles of any substance will be defined as:

n = W / M

Given chemical reaction is:

CaCO₃ → CaO + CO₂

From the above equation it is clear that according to the concept of stoichiometry 1 mole of CaCO₃ is producing 1 mole of CaO. By using above formula, we calculate grams as follow:

W = n × M, where

n = no. of moles of CaO = 3.9 moles

M = molar mass of CaO = 56 g/mole

W = 3.9 × 56 = 218.4 g

Hence, 218.4 grams of Cao is produced.

<h3>How much grams do Cao's molecular weight equal?</h3>

Molecular weight of CaO. CaO has a molar mass of 56.0774 g/mol. Calcium Oxide is another name for this substance. Convert moles of CaO to grams or grams of CaO to moles. Calculation of the molecular weight: 40.078 + 15.9994 ›› Composition by percentage and element

<h3>How much calcium is required to create one mole of oxygen?</h3>

In order to create one mole of calcium oxide, the reaction between one mole of calcium (40.1 g) and half a mole of oxygen (16 g) is stoichiometric (56.1 g). This means that only 4.01 grams of calcium metal and 1.6 grams of oxygen can combine to generate 5.61 grams of calcium oxide.

A student measures the mass of a 6.0 cm3 block of brown sugar to be 10.0 g. What is the density of the brown sugar?
Alex17521 [72]

Answer:

1.67g/cm3

Explanation:

The formula for density is d=\frac{m}{v} . The m variable stands for mass and the v variable stands for volume.

The mass of the brown sugar is 10.0g and the volume is 6.0cm3, so we can plug those values into the equation.

d=\frac{10g}{6cm^{3} }

d=1.67\frac{g}{cm^{3} }

Rounded to 3 significant figures, the density of the block of brown sugar is 1.67 g/cm3. If the mass is in grams and the volume is in cm3, the unit for the final answer is \frac{g}{cm^{3} } (grams per centimetres cubed).
