How many sucrose molecules will be in 250 grams
sasho [114]
<h2>Answer:</h2>

We will need to know Avogadro's number and the molar mass of sucrose for this problem to do dimensional analysis.

  • Avogadro's number: 6.022 × 10²³ molecules
  • Molar mass of sucrose: 342.2965 g/mol

250g × \frac{1 mol}{342.297g} × \frac{6.022 * 10^{23} molecules}{1 mol} = 4.398 molecules

There are <em>4.398 sucrose molecules </em>in 250 grams of sucrose.

53. A firefighter of mass 80 kg slides down a vertical pole
Zielflug [23.3K]

Answer:

Answer is given below:

Explanation:

<em>Given Data:</em>

mass = 80kg

acceleration = 4 ms

force = 800N

<em>Find out:</em>

friction = ?

<em>Formula</em><em>:</em>

F-friction = weight - f-net

<em>Solution:</em>

weight = (80)(10)

           = 800 N

F-net = ma =(80)(4) = 320N

F-friction = weight - F-net

               =800 N - 320N

               =480N

<em>Answer</em> :

Friction = 480 N
