What mass of ni has as many atoms as there are n atoms in 63.0 g of no2?

adoni [48]

Answer : The mass of Ni is, 80.346 g

Solution :

First we have to calculate the number of moles.

$\text{Moles of }NO_2=\frac{\text{Mass of }NO_2}{\text{Molar mass of }NO_2}=\frac{63g}{46g/mole}=1.369moles$

Now we have to calculate the number of atoms of $NO_2$

As 1 moles $NO_2$ contains $6.022\times 10^{23}$ number of molecules

So, 1.369 moles $NO_2$ contains $1.369\times 6.022\times 10^{23}$ number of molecules

One $NO_2$ molecule has one nitrogen atom then $1.369\times 6.022\times 10^{23}$ number of molecules of $NO_2$ will contain $1.369\times 6.022\times 10^{23}$ number of nitrogen atoms

As per question number of Ni atoms is equal to the number of nitrogen atoms

Number of Ni atoms= $1.369\times 6.022\times 10^{23}$ atoms

Number of moles = $\frac{1.369\times 6.022\times 10^{23}}{6.022\times 10^{23}}=1.369moles$

Mass of Nickel = $Moles\times \text{Molecular mass}}$

Molecular mass of Nickel = 58.69 g/mol

Mass of nickel = $1.369mol\times 58.69g/mol=80.346grams$

If a house viewed through infrared goggles ,where would the most seen

Serjik [45]

Answer:

The answer is D - near the roof.

Explanation:

Attics don't have a ton of insulation or hard cinder-block to block the goggles form seeing through it. This is why the attic can be a place where the temperature varies with the outside temperature.

When the pressure that a gas exerts on a sealed container changes from 22.5 psi to ? psi, the temperature changes from 110 degre

natta225 [31]

Using Gay-Lussac's Law, pressure is proportional to (absolute) temperature in Kelvin. We first convert the temperature values to Kelvin: 110 C = 383.15 K, while 65 C = 338.15 K.
P1/T1 = P2/T2
22.5/383.15 = P2/338.15
P2 = 19.9 psi
