When performing a gram stain, it is necessary to remove crystal violet stain from any gram negative bacteria on the slide. Micro
Snezhnost [94]

Answer:

10.11 mL

Explanation:

Given that :

Total volume of decolorizer = 500 mL

A common recipe is equal parts 95% ethanol and acetone.

So;

The volume of 95% ethanol in the decolorizer = 500mL/2 = 250 mL

Let represent V(ml) for the 99% of ethanol needed to make 95% of the 250 mL of ethanol;

Therefore:

V(ml) × 0.99 = 250 × 0.95

V(ml) × 0.99 = 237.5

V(ml)  = 237.5/0.99

V(ml) = 239.89 mL

Hence; the amount of water to be added to 95% of ethanol = ( 250 -  239.89 )mL = 10.11 mL

How many grams of NCI3<br> are in 4.00 moles of NC13?
TEA [102]

The mass of NCl3 in 4.00 moles of NCl3 is 481.44 grams

Mole is defined as the amount of the substance containing the same number of discrete entities (atoms, molecules, ions, etc) as there are atoms in a sample of pure 12C weighing exactly 12g. The number of particles present in one mole of any substance =Avogadro Number=6.

The formula for number mole is given as:

Number of moles =  <u>Mass of the substance </u> ; Now substituting the values

                                   Molar mass

⇒ 4.00 =  <u>x        </u>                       [Molar mass of NCl3 = 120.36]

               120.36

⇒ x = 4.00 × 120.36

⇒ x = 481.44 grams

Therefore the mass of NCl3 is 481.44 grams

A frisbee is moving at 11 m/s and has 3.6j of energy. how much does it weigh?
Ber [7]

Answer:

0.06 kg

Explanation:

Given data:

Mass of frisbee = ?

Velocity of frisbee  = 11 m/s

Energy of frisbee = 3.6 j

Solution:

K.E = 1/2 mv²

Now we will put  the values in this formula.

3.6 J = 1/2 m(11m/s)²

3.6 j = 0.5 ×121m²/s² × m

3.6 j = 60.5 m²/s² × m

m = 3.6 j/60.5 m²/s²

m= 0.06 j.m⁻².s²

j = Kg.m².s⁻²

m= 0.06 Kg.m².s⁻² .m⁻².s²

m = 0.06 kg

How many fluorine atoms are in 750.0 mL of a 0.500M HF solution?
SIZIF [17.4K]

Answer:

2.26 \times 10^{23}atomsF

Explanation:

Step 1: Given data

  • Molarity of the HF solution (M): 0.500 M
  • Volume of the solution (V): 750.0 mL

Step 2: Convert "V" to liters

We will use the conversion factor 1 L = 1000 mL.

750.0 mL × 1 L/1000 mL = 0.7500 L

Step 3: Calculate the moles of HF

We will use the following expression.

n = M × V

n = 0.500 mol/L × 0.7500 L = 0.375 mol

Step 4: Calculate the atoms of F in 0.375 moles of HF

We will use the following relationships:

  • 1 mole of HF contains 1 mole of atoms of F.
  • 1 mole of atoms of F contains 6.02 × 10²³ atoms of F (Avogadro's number).

0.375 mol HF \times \frac{1 mol F}{1 molHF} \times \frac{6.02 \times 10^{23}atomsF }{1 mol F} = 2.26 \times 10^{23}atomsF
