Indicate whether the statements below are TRUE or FALSE. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. 1. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose. 2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower. 3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration

Indicate whether the statements below are TRUE or FALSE.
You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them.
1. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.
