The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abb
Nimfa-mama [501]

Answer:

\boxed{\text{254 g}}

Explanation:

\begin{array}{rcl}\text{\% m/V} & = & \dfrac{\text{Mass of sucrose}}{\text{Volume of solution}}\\\\\text{Let m}& = &\text{mass of sucrose}\\\dfrac{\text{35.0 g}}{\text{100 mL}}& = & \dfrac{m}{\text{725 mL}}\\\\m & = &\dfrac{\text{35.0 g}\times 725}{100}\\\\ & = &\textbf{254 g}\\\end{array}\\\text{You need $\boxed{\textbf{254 g}}$ of sucrose}

What are the benefits and limitations to relative dating rock layer?
vlabodo [156]
Relative dating can only determine the sequential order<span> of events, not the exact date which something occurred. It is useful for being able to determine a timeline of events in an exact point, but won't give a full picture of events in the past nor account for the age of material.

Determine the mass of KNO3 that dissolves in 100 grams of water at 40°C to produce a saturated solution
velikii [3]
From a solubility curve the solubility of KNO3 at 40°C is about 63 g / 100 g of water.


That means that 100 g of water at 40°C can dissolve 63 g of KNO3.


A saturated solution is one that cannot dissolve more solute, because it already has reached the greatest concentration that it can hold.


Then, the mass of KNO3 that dissolves in 100 g of water is about 63 g.

In the bohr model of the hydrogen atom, how does the radius of the electron’s orbit depend on the principal quantum number?
wolverine [178]
The radius of the electron's or basically the energy level for which the electron is found orbiting the nucleus of he hydrogen atom, as the principal quantum number tells us primarily the energy level that the electron will be found, is it the 1st, 2nd, and 3rd. The other quantum numbers tells us more specifically as per the subshell of the main shell the electron is in, the spin of the electron etc.

What mass of CH3COOH is present in a 250 mL cup of 1.25 mol/L solution of vinegar?
aleksley [76]
If    1000 ml (1 L) of CH₃COOH contain 1.25 mol
let  250 ml  of CH₃COOH contain x

⇒  x =  \frac{250 ml * 1.25mol}{1000 ml}
        
        =  0.3125 mol

∴ moles of CH₃COOH in 250ml is 0.3125 mol

Now, Mass = mole  ×  molar mass
        
                   = 0.3125 mol  × [(12 × 2)+(16 × 2)+(1 × 4)] g/mol
 
                   = 18.75 g

∴ Mass of CH₃COOH present in a 250 mL cup of 1.25 mol/L solution of vinegar is <span>18.75 g</span>
