Help I’m literally failing I need help

You just simply need to divide the mass by the molar mass to get your moles! :)

1) determine molar mass

= 24.31 + 32.07 + 4(16.00)

= 120.38 g/mol

2) solve

n = 0.292 moles MgSO₄

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
