What is the mass, in grams, of 0.0287\,\text {mol}0.0287mol0, point, 0287, start text, m, o, l, end text of sucrose? Express the answer using 3 significant figures.

This sample of sucrose has a mass of 9.82 grams

Explanation:

Step 1: Data given

The molecular weight of sucrose = 342.30 g/mol

The number of moles of this sucrose sample = 0.0287 moles

Mass = moles * molar mass

Step 2: Calculate the mass of this sucrose sample

Mass sucrose = moles sucrose * molar mass sucrose

Mass sucrose = 0.0287 moles * 342.30 g/mol

Mass sucrose = 9.82401‬ grams

When we express this amount using 3 significant figurse we have:

Mass sucrose = 9.82 grams

This sample of sucrose has a mass of 9.82 grams

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
