Molecular mass is the sum of the masses of all the individual atoms present in a molecule or compound. Carbon dioxide is an acidic gas which releases during respiration. The chemical formula of Carbon dioxide is CO 2. The atomic mass of Carbon C is 12 u. The atomic mass of hydrogen H is 1 u.
(Relative molecular mass of calcium carbonate is 100). (iii) What is the volume of carbon dioxide liberated at stp? (iv) What mass of calcium chloride is formed? (Relative molecular mass of calcium chloride is 111) (v) How many moles of HCl are used in this reaction?
Carbon Disulfide Reactions. Reacts with oxygen produce carbon dioxide and sulfur dioxide. CS 2 + 3 O 2 → CO 2 + 2 SO 2. Sodium sulfide undergoes a reaction to produce trithiocarbonate: Na 2 S + CS 2 → [Na +] 2 [CS 3 2−] Carbon disulfide is reduced with sodium to produce sodium 1,3-dithiole-2-thione-4,5-dithiolate and sodium trithiocarbonate.
A vessel contains a mixture of nitrogen (m 1 = 7.0 g) and carbon dioxide (m 2 = 11 g) at a temperature T = 290 K and pressure p 0 = 1.0 atm. Find the density of this mixture, assuming the gases to be ideal.
Molecular mass of carbon dioxide = 44g; Therefore , the mass of 1 mol of CO 2 is 44g. As per Avogadro's rule, 1 mol of substance has 6. 022 × 10 23 molecules. Therefore mass of 6. 022 × 10 23 molecules of CO 2 is 44g. Hence, the mass of 1 molecule of CO 2 is = 44 6. 022 × 10 23 = 7. 306 × 10-23 g
Using the formula, n = m MWheren = number of molesm = given mass of carbon dioxide = 22 gM = Molar mass of carbon dioxide = 44 gSo, n = 22 44 = 0.5 molesTherefore, 22 g carbon dioxide = 0.5 moles. Suggest Corrections. 181.

Calculate the mass of oxygen produced when 2.45 g of KO2 and 4.44 g of CO2 react. KO2 +CO2 → K2CO3 +O2 (yield = 80 %) (Molar mass of K = 39 g/mol) View Solution. Click here:point_up_2:to get an answer to your question :writing_hand:calculate the molar mass of displaystyle co 2.
The mixture of gases that makes up the Earth’s atmosphere is known as air. Nitrogen makes up 78 % of this gas, which is mixed with oxygen (21%), water vapour (variable), argon (0.9 %), carbon dioxide (0.04%), and trace gases. There is no apparent scent or colour in pure air. Dust, pollen, and spores are common contaminants in the air ...
