Answer:

1368 grams

Explanation:

Molar Mass of malt sugar (C12H22O11) = 342 g

Molarity=  342 g/ mol

so 1 molar solution contain =   342 g /Liter

4 Molar solution  contain=  1368g / Liter

Answer:

1368 grams.

Explanation:

Molarity is defined as number of moles of solute present in one litre of solution. 1-M means 1 mole of solute is present in 1 litre of solution.

4-M solution means 4 moles of solute is present in 1 litre of solution.

Molar mass of C_{12}H_{22} O_{11} = 12 \times 12 + 22 \times 1 + 11 \times 16 = 342 grams.

as molar mass of carbon,hydrogen and oxygen atoms are 12,1 and 16 grams respectively.

Since molar mass of C_{12} H_{22} O_{11} is 342 grams,

1 mole of it weighs 342 grams and 4 moles of it weighs 4 \times 342 = 1368 grams.

Hence we need 1368 grams to make a 4-M solution of C_{12}H_{22} O_{11}.

What is dual behaviour of matter​
Andrej [43]

Answer:

Dual nature of matter is an important concept in JEE physics and is basically the study of different nature that a matter possesses or exhibits. ... Hence, the matter is said to possess dual nature, i.e., it has both the properties of a particle and as well as a wave.

Write the balanced chemical equation for the reverse reaction. include physical states for all species.
Ann [662]
This is a missing part of your question:
The equilibrium system between sulfur dioxide gas, oxygen gas, and sulfur trioxide gas is given.
So you need the equilibrium balanced equation of SO2, O2, SO3 reaction:
First, we will start with the original equation which is not balanced yet (to understand how we get it):
SO2 + O2 ↔ SO3 
Here the number of O atom is not equal at the to sides
So we will start to balance our equation by make the number of O atom equal each other on both sides:
So we will start to put 2SO3 instead of SO3 
and put 2SO2 instead of SO2 to balance also the S atom on both sides
So we will get this:
2SO2(g) + O2(g) ↔ 2SO3(g) (This is our equilibrium balanced equation)
know we have a number of O atom equals on each side = 6
and the sulfur equals on each side = 2
