Answer:
Hello your question is incomplete attached below is the complete question
answer: wt.% of alloy that is solid = 61.5%
wt.% of allot that is liquid = 38.5%
Explanation:
To determine the wt.% of the alloy that is solid
= [tex]\frac{R}{R +S } * 100[/tex]
= [tex]\frac{53-45}{58-45} * 100[/tex] = 61.5%
To determine the wt.% of the alloy that is liquid
= [tex]\frac{S}{S+R} * 100\\[/tex]
= [tex]\frac{58-53}{58-45} *100[/tex] = 38.5%
