3) If an electrical appliance has 150.0 V applied causing a current of 2.34 amps, what is the
eimsori [14]

The resistance of the appliance is 64.1 Ω.

<u>Explanation:</u>

As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,

V = IR

Where V is the voltage (V) = 150.0 V

I is the current (amps) = 2.34 amps

R is the resistance (ohm) or Ω = ?

Now we have to rearrange the equation to get the resistance as,

$R = \frac{V}{I}

Now we have to plug in the values as,

$ R = \frac{150}{2.34}

   = 64.1 Ω

So the resistance of the appliance is 64.1 Ω.

Quiero saber Que es un isótopo?
Kamila [148]
Son átomos que tienen el mismo número atómico, pero diferente masa atómica. Es decir, contienen el mismo número de protones pero difieren en el número de neutrones. Como ejemplo, tendríamos el Hidrógeno y sus 3 isótopos, el Protio, el Deuterio y el Tritio.

At − 12.0 ∘ C , a common temperature for household freezers, what is the maximum mass of sorbitol (C6H14O6) you can add to 2.00
allochka39001 [22]

Answer:

2,347.8 grams

Explanation:

The freezing point depression Kf of water = 1.86° C / molal.

 

To still freeze at -12° C, then the molality of the solution 12/ 1.86 = 6.45 moles

 

The molecular weight of sorbitol (C6H14O6)is:

 

6 C = 6 ×12 = 72

14 H = 14 × 1 = 14

6 O = 6 × 16 = 96

...giving a total of 182

 So one mole of sorbitol has a mass of 182 grams.

 

Since there are 2 kg of water,  2 × 6.45 moles = 12.9 moles can be added to the water to get the 12° C freezing point depression. 

Therefore

grams = moles × molar mass

12.9 moles × 182 grams / mole = 2,347.8 grams of sorbitol can be added and still freeze

How many grams of water (H2O) are there in 2.60 mol of the compound?
ad-work [718]

Answer:

46.839728  grams of water

Explanation:

1 mole is equal to 1 moles H2O, or 18.01528 grams

18.01528 times 2.6 = 46.839728

There are 46.839728  grams h20 in 2.60 mol of the compound
