Can somone help me plzzzzzzzzzzzzz

Answer 1

Answer:

$\huge \fbox \pink {A}\huge \fbox \green {n}\huge \fbox \blue {s}\huge \fbox \red {w}\huge \fbox \purple {e}\huge \fbox \orange {r}$

$\huge\red{ \mid{ \underline{ \overline{ \tt Fe }} \mid}}$

→ Molar Mas = 55.85 g/mol

$\huge\orange{ \mid{ \underline{ \overline{ \tt NaCl }} \mid}}$

→ Molar Mass = 58.44 g/mol

$\huge\red{ \mid{ \underline{ \overline{ \tt CH₄ }} \mid}}$

→ Molar Mass = 16.02 g/mol

$\huge\orange{ \mid{ \underline{ \overline{ \tt Ca(OH)₂ }} \mid}}$

→ Molar Mass = 74.10 g/mol

Answer 2

Answer:

Fe -> 55.85g/mol

NaCl-> 58.44g/mol

CH₄->16.02g/mol

Ca(OH)₂->74.10g/mol

Explanation:

NaCl = 22.990 + 35.45  = 58.44g/mol

CH₄ = 12.011 + (1.008 × 4) = 16.043 g/mol

Ca(OH)₂ = 40.078  + 2(15.999 + 1.008) = 74.092 g/mol
