The answer to this question would be: 3 molar
A molar unit will be equal to moles of solute per 1 liter of solvent. In this question, you are given the volume of the solution (264.8ml) and the weight of the molecule(139mg). Since the unit is moles not mg, then you need to convert the molecule into moles. To do that you need to know the ascorbic acid molecular weight which was: 6*12 + 8*1 + 6 *16 =<span>176mg/moles.
molecule in moles= 139mg/ (176 mg/moles)= 0.79 moles
Then the molarity of the juice should be: 0.79 moles/ (1000ml/264ml)= 2.991 M= 3 M</span>
Explanation:
Hey It is due to physical properties
The hydrogen bonds that hold water molecules together in water's liquid and solid form give the substance high boiling and freezing points and strong surface tension. Because water molecules are held so tightly together, it takes a large amount of heat for water to boil.

Hi mate. I think the answer is 100
Answer:
9.82 g of Mg(NO₃)₂
Explanation:
Let's determine the reaction:
2AgNO₃ + MgBr₂ → Mg(NO₃)₂ + 2AgBr
2 moles of nitrate silver reacts with MgBr₂ in order to produce 1 mol of magnesium nitrate and silver bromide.
We determine the moles of AgNO₃
22.5 g . 1mol / 169.87g = 0.132 moles
Ratio is 2:1.
2 moles of silver nitrate can produce 1 mol of magnesium nitrate
Then, our 0.132 moles may produce (0.132 . 1)/ 2 = 0.0662 moles
We convert moles to mass:
0.0662 mol . 148.3 g/ mol = 9.82 g
