How many moles are in 3.3 moles of K2S?
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
How many moles of cations are in 1.30 mol of rmK 2 rmSO 4?
2.60 moles There are 2 moles of K in K2SO4. the total moles times two (1.3 x 2) is 2.60 moles.
How many grams in 1.90 moles of K?
To convert from moles to grams, we need to use the molar mass of the element. The molar mass of potassium (K) is approximately 39.10 g/mol. So, for 1.90 moles of K, the mass would be 1.90 moles * 39.10 g/mol = 74.29 grams.
How many moles of cations are in 1.45 mol of K2SO4?
In the K2SO4 equation, SO4 is not a cation since it consists of negatively charged ions. So K+ is the only cation, and since there are two of them then it is 2 mole K+ per mole K2SO4 . So 2 x 1.55 = 3.10 mol K+
How many moles are of H2O are needed to react completely with 7.54 mol of K?
The balanced chemical equation for the reaction between water (H2O) and potassium (K) is: 2K + 2H2O -> 2KOH + H2. 1 mole of potassium (K) reacts with 1 mole of water (H2O). Therefore, 7.54 moles of potassium would react with 7.54 moles of water.
How many moles in k2co3 in 0.5 moles?
If you have 0.5 moles of K₂CO₃, then you simply have 0.5 moles of K₂CO₃. The quantity of moles is a direct measurement, so there are no additional calculations needed. Therefore, the answer is 0.5 moles of K₂CO₃.
How many moles are in 3.3 moles of K2S?
3.3 moles of K2S 3.3 moles of S-2 6.6 moles of K+1
How many atoms are in 0.3 moles of potassium?
0.3 moles K (6.022 X 10^23/1mol K) = 1.8 X 10^23 atoms of K
How many moles are there in a 3 L container at 1 ATM pressure and 293 K?
The answer is 0,125 moles.
How many moles of air are there in a 3 L container a 1 ATM pressure and 293 K?
0.125 moles
How many moles of cations are in 1.30 mol of rmK 2 rmSO 4?
2.60 moles There are 2 moles of K in K2SO4. the total moles times two (1.3 x 2) is 2.60 moles.
How many atoms of potassium need to react with nitrogen in order to produce 2.0 moles of potassium nitride?
To produce potassium nitride (K₃N), the balanced chemical equation is 6 K + N₂ → 2 K₃N. This indicates that 6 moles of potassium are required to produce 2 moles of potassium nitride. Therefore, to produce 2.0 moles of K₃N, you would need 6 moles of potassium.
How many moles of gas occupy 1.3 L at a pressure of 3.89 atmospheres and a temperature of 323 K?
The answer is 0,19 moles.
How many grams in 1.90 moles of K?

How many 1000 K equals Fahrenheit?
1000 Kelvin = 1,340.33 Fahrenheit
How many moles of potassium oxide (K2O) will be formed when 1.52 moles of potassium reacts with oxygen according to the following reaction 4 K O2 2 K2O?
According to the reaction (4 \text{K} + \text{O}_2 \rightarrow 2 \text{K}_2\text{O}), 4 moles of potassium produce 2 moles of potassium oxide (K2O). Thus, the mole ratio of potassium to K2O is 4:2, or 2:1. If 1.52 moles of potassium are used, the number of moles of K2O formed can be calculated as (1.52 , \text{moles K} \times \frac{2 , \text{moles K2O}}{4 , \text{moles K}} = 0.76 , \text{moles K2O}). Therefore, 0.76 moles of potassium oxide will be formed.
