Atomic masses à H(1), O(16), N(14), C(12), K(39), S(32) Ca(40), Na(23), Cl(35.5),Mg(24), Al(27)Molecular formulae NaCl, MgCl2, KNO3, H2O2, AlCl3, Ca(OH)2 , MgO, H2SO4, HNO3, NaOH​

Answer»

Answer:

NaCl=23+35.5=58.5g. MgCl2= 24+70=94g. KNO3=39+14+48=101 G. H2=2g.

O2=32g.

AlCl3=27+106.5=133.5g. Ca(OH)2= 40+32+2=74g. MgO=24+16=40g. SO4=32+64=96g. HNO3=1+14+48=63g. NAOH= 23+16+1=40 g. This is the CALCULATION Of molecular weight If we particular element weight we can Calculate easily...... i attached there picture Of periodic Table there u can find masses of any element Plz MAKE my answrr branliest
