The Book of Mormon says that there are no chances for salvation after death:
"Therefore, if that man repenteth not, and remaineth and dieth an enemy to God, the demands of divine justice do awaken his immortal soul to a lively sense of his own guilt, which doth cause him to shrink from the presence of the Lord, and doth fill his breast with guilt, and epain, and fanguish, which is like an unquenchable fire, whose flame ascendeth up forever and ever. And now I say unto you, that mercy hath no claim on that man; therefore his final doom is to endure a never-ending torment." (Mosiah 2:38-39)
The Doctrine and Covenants, on the other hand, affirms the idea of postmortem salvation:
"And after this another angel shall sound, which is the second trump; and then cometh the redemption of those who are Christ’s at his coming; who have received their part in that prison which is prepared for them, that they might receive the gospel, and be judged according to men in the flesh." (section 88:99)
