Answer:
59.42 ×10²³ formula units
Explanation:
Given data:
Number of moles of NH4NO3 = 9.87 mol
Number of formula units = ?
Formula:
Number of formula units = moles × Avogadro number
Solution:
Avogadro number = 6.02×10²³
Number of formula units = 9.87 × 6.02 ×10²³
Number of formula units = 59.42 ×10²³ formula units
Answer:
Explanation:
Here, we want to check if the equation of the reaction is balanced or not
Now, for a balanced equation of reaction, the number of atoms of the individual elements on both sides of the equation is equal
Now, let us check the atoms:
We have 1 Sr on both sides
We have 1 SO4 on both sides
We have 1 Mg on both sides
We have 2 OH on both sides
From what we can see, the equation of the reaction is balanced
Thus, the correct answer choice is B
Answer: V= 1.87 L
Explanation: Use Charles Law to solve for the new volume.
V1/T1 = V2/T2 where temperature is in Kelvin. So convert temperature to Kelvin.
4 L ( 175 K ) / 375 K
= 1.87 L
Cancel out both units of K.
