What is the mass of frutose also known as fruit (c6h12o6) in a 1.40×10^2ml sample of glucose solution that has a concentration of a 1.23m?

m = 129,96 g

Explanation:

c = n / V

n = c * V

n = 1,23 mol/l * 0,14 l

n = 0,722 mol

n = m / M

m = n * M

m = 0,722 mol * 180 g/mol

m = 129,96 g

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
