You will use mass=mole x Molar mass
The molar mass of Na2CO3 is 106
So 0.45 x 106 = 47.7 grams

To convert moles to grams, we need the molar mass of the molecule

molar mass of Na₂CO₃= (2 x 23.0) + 12.0 + (3 x 16.0)= 106 g/mol

$0.450 mol \frac{106 grams}{1 mol} = 47.7 grams$

asambeis [7]

The balanced equation for the generation of sugar from sunlight water and CO₂ is

6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂

carbon dioxide + water → sugar + oxygen

<span>The process of photosynthesis occurs when the chlorophyll present in the leaves of plants absorb sunlight to make food in the presence of carbon dioxide (enters through the stomata of leaves) and water (absorbed from the roots). As a result of this reaction sugar and oxygen is formed. After that sugar is converted in to starch and oxygen is released into air.</span>
