Empirical formula is a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.
so, in this case :
ratio of x to y is 6:3 or 2:1 . Empirical formula would be
Answer:
Explanation:
Simply
Coal has two valent electrons, so there is 2 in 2p orbital
Hi! Are you looking for molarity?
Answer:
1.38g/cm 3
Copper-More Dense than 1.38g/cm 3
Answer:
2.34g of NaCl
Explanation:
HCl(aq) + NaOH(aq) --------> NaCl(aq) + H2O(l)
Number of moles of HCl= 8 × 5/1000= 0.04 moles
Number of moles of NaOH= 2.4 × 20/1000= 0.048 moles
HCl is the limiting reactant
From the balanced reaction equation, 1 mole of HCl produced 58.5g of NaCl
0.04 moles of HCl will produce 0.04 × 58.5 = 2.34g of NaCl
